Online published on 8 August, 2019. Abstract The present study was designed to extract nasunin and evaluated the effect of phytochemicals preset in different varieties of eggplants in Tamil Nadu, India. In vitro analysis of antioxidant activity of DPPH radical scavenging, reducing properties were analyzed in different varieties. The biochemical constituents of carbohydrates, proteins, lipids, dietary fibre and total phenol contents of both the ripe and unripe eggplant were also evaluated. The results indicate that purple color eggplant showed higher amount of nasunin antioxidants and phenolics than white colored varieties However, both purple and white colored varieties of eggplant exerted similar free radical scavenging activity and reducing property. We concluded that when consumed both varieties of green and purple coloured varieties of eggplant can be considered as potential bioactive compounds and antioxidant sources were identified by HPLC and GC-MS.
